Logging and contesting on Linux: CQRLOG, Win-Test (under wine) and sometimes the good old tlf.

Other: My QTH is plagued by occasional power line -like noise, which is S3 on most bands. While the noise blanker takes it down completely, the settings must be cranked up causing distortion and interference from the nearby strong signals. So, if I can't hear you well, be patient and, if on CW, drop the WPM rate. Also, it does not help that I am located in a valley with mountains very close to SW-S-E-N directions.
